A. To understand the nature of an experimental subject
The phase during which sister chromatids aggregate along the equator of the cell is called the metaphase.
The image shows the process of cell division through mitosis. The mother cell divides into two genetically identical daughter cells in mitosis. There are four main phases in the mitosis process. They are: prophase, metaphase, anaphase and telophase. In the metaphase, the highly condensed sister chromatids line up along the equator of the cell by binding to the microtubles that form the skeleton of the cell. These kinetochores line up the chromatids at the equator to initiate their separation.
Answer:
1/4
Explanation:
Let the earlobe allele be represented by A. since the attached earlobe is the recessive trait, the genotype would be aa while the free earlobe would be AA. The heterozygous condition would be Aa.
Two individuals heterozygous for free earlobes mated:
Aa x Aa
AA Aa Aa aa
AA and Aa = Free earlobe = 3/4
aa = attached earlobe = 1/4
<em>Hence, the probability of the couple having a child with an attached earlobe is </em><em>1/4.</em>
